In particular, we address the capacity limitations of backpressure networks within fading en- vironments by the retasking of a cooperating node as a relay with potentially heterogeneous transmission architecture. Retasking a node as a cooperative relay can temporally allocate resources of one particular session within the backpressure network onto another session, thereby allowing for a more flex- ible physical (PHY) layer for traffic load balancing. With this, we derive a scheduling method that ensures timely delivery of information in networks without predetermined infrastructure. Within this thesis, we propose the architecture of an amplify-and-forward relay for cooperative communications and derive the performance of multi- ple cooperative nodes utilizing this architecture. We also propose a suitable medium access control (MAC) layer facilitating the scheduling and decision making of nearby relay node candidates. The proposed architecture may be of potential interest for emerging device-to-device (D2D) and swarming mesh networks.","Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-12-01","The student, Ulysses Lee, accepted the attached license on 2016-12-06 at 15:48.","The student, Ulysses Lee, submitted this Thesis for approval on 2016-12-06 at 15:58.","This Thesis was approved for publication on 2016-12-07 at 09:42.","DSpace SAF Submission Ingestion Package generated from Vireo submission #10457 on 2017-02-28 at 14:37:21"]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Backpressure networks with cooperative link augmentation"]}]}],"canonical_facts":{"dc:contributor":["Singer, Andrew Carl"],"dc:creator":["Lee, Ulysses"],"dc:date":["2017-03-01T16:37:08Z","2019-03-02T10:15:24Z","2016-12-07","2016-12"],"dc:description":["Made available in DSpace on 2017-03-01T16:37:08Z (GMT).
